Ok, I know I’ve asked this before on a forum someplace, but I’m still trying to figure out the right answers. What does a 802.11b sniffer on a 802.11g network see, and vice versa using both Promiscuous mode and Monitor mode? For those that don’t understand the difference between the two modes read:

Promiscuous mode http://en.wikipedia.org/wiki/Promiscuous_mode
Monitor mode http://en.wikipedia.org/wiki/Monitor_mode

Seems a lot of folks get them confused. To further complicate the matter, some cards seem not to support these modes (for example, ipw2200 supports Monitor with the newest drivers in Linux but does not seem to support Promiscuous in Windows or Linux for what I have tried so far, at least in the distribution I’m using). Here are my questions, but in a more concise manner:

1. 802.11b sniffer on a 802.11g network see when in Monitor mode?
2. 802.11b sniffer on a 802.11g network see when in Promiscuous mode?
3. 802.11g sniffer on a 802.11b network see when in Monitor mode?
4. 802.11g sniffer on a 802.11b network see when in Promiscuous mode?

I plan to do some systematic tests soon and post results, but my hardware is limited and as I stated before, lack of support with some chipsets does complicate maters. As best as I can tell so far these may be the answers:

1. Just 802.11 management traffic (beacons and such) and broadcast traffic.
2. Just broadcast traffic.
3. Everything.
4. Everything but 802.11 management traffic (beacons and such).

Also, if anyone can recommend a good 802.11G card that will support Promiscuous in Windows and Monitor in Linux I would appreciate it. I’ve found sites that recommend good cards, but sometime the revision numbers can cause confusion as to what modes are supported.
